Carrier Board Design Guides
This article helps you find the layout guide, design guides for each module family, and tools for developing a custom carrier board for Toradex System on Modules (SoMs). Use the layout guide for board layout considerations and the guide for your module family for interface details and reference schematics.
Carrier Board Layout Guideā
The Carrier Board Layout Guide covers:
- Printed circuit board (PCB) stack-up: four-layer, six-layer, and eight-layer stack-ups
- Trace impedance
- Component placement and schematic optimizations
- High-speed layout considerations: power supply, trace bend geometry, signal proximity, trace stubs, ground planes under pads, differential pair signals, length matching, signal return path, and analogue and digital ground
- How to avoid signal integrity and electromagnetic compatibility (EMC) issues on the carrier board
- Layout requirements of interfaces, such as:
- Connectivity and storage interfaces: PCI Express, SATA, Ethernet, USB, SD/MMC/SDIO
- Video interfaces: Parallel RGB LCD, LVDS LCD, HDMI/DVI, Analogue VGA, Display Serial Interface (MIPI/DSI with D-PHY)
- Camera interfaces: Parallel Camera, Camera Serial Interface (MIPI/CSI-2 with D-PHY)
- Low-speed interfaces: IĀ²C

Toolsā
Use the Pinout Designer Tool to plan pin assignments and check module compatibility. For Colibri modules, the Compatibility Guide is an Excel file that compares module pin functions and RGB display and camera input color mappings.
Upverterā
Upverter is an online carrier board design tool that simplifies carrier board design and software support at the BSP level. The tool is available on the Toradex developer website:
